Just bought flights to USA and my daughters passport is expired 😵‍💫 dual citizenship all of us

So we’re supposed totally travel December 15th and her passport is expired. She’s 12 yrs old. I managed to get a passport service time for the us embassy here in my home country for November 25th. Can she travel with an old passport if we don’t somehow manage to get a new one in time or with her Scandinavian passport? We all have dual citizenships.
